Blanco County, Texas: It's the week before deer-hunting season and the locals are getting restless. Game Warden John Marlin has his hands full with poaching complaints coming in faster than he can write tickets. Then a call of a different sort comes in. A man in some sort of deer costume has been shot, and witnesses are reporting a wild-eyed buck prancing about the pasture in a lovesick frenzy. Marlin's seen a lot in his years, but this is wilder than he could have imagined: the man in the deer suit is a good friend, and the whacked-out whitetail isn't a stranger either. It's the beginning of a frantic weekend in Blanco County, one that will see a few more men shot, an invasion by Colombians with more than hunting on their minds, and damn near the end of Marlin's life.
